Greg and Jeff are walking down the street when a student drops two identical flower pots from a second story window, one pot hitting Greg and one pot hitting Jeff. The flower pot that hits Jeff bounces up off his head with the same speed that it had before it hit him. The flower pot that hits Greg does not bounce. If the time interval involved in both collisions is the same, then which statement is true? The average force exerted on Greg's head is greater than the average force exerted on Jeff's head. The average force exerted on Greg's head is less than the average force exerted on Jeff's head. The average force exerted on Greg's head is the same as the average force exerted on Jeff's head.
